The Office of the Comptroller of the Currency fined the bank in late December and announced it on Thursday. The regulator assessed the civil penalty because the bank had failed to address concerns it had first flagged in 2012.

A spokesman for the bank, a unit of Citigroup Inc (C.N), said it aimed to satisfy all federal rules that target money laundering.

“Citi is committed to taking all necessary and appropriate steps to remedy the concerns identified by the OCC,” said spokesman Mark Costiglio.
